Let Us Know What You Need
1.Retro-reflective, Diffuse-reflective, and BGS-reflective Models are also available with a 5-m pre-wired cable. When ordering, add the cable length to the end of the model number (e.g., E3ZM-CD62 5M).
2.Models with no moving parts (i.e., without a sensitivity adjustor or mode selection switch) are also available, as are models with built-in slits (through-beam, 0.8 m) (e.g., E3ZM-CT83H 2M for no sensitivity adjustment, wire-connection selection of operation mode, and built-in slit).
3.All models are available with 3-pin or 4-pin M8 connectors, e.g., E3ZM-CT66 (M8 4-pin).
4.Through-beam Models are also available with a light emission stop function. When ordering, add “-G0” to the end of the model number (e.g., E3ZM-CT61-G0).
Ask your OMRON representative for details on any models or specifications you require.

Reflector
| Name | E3ZM-CR sensing distance (typical) * | Model | Quantity | Remarks |
| Reflector | 3 m (100 mm) (rated value) | E39-R1 | 1 | Reflectors are not provided with Retroreflective models. The MSR function is enabled. |
| 4 m (100 mm) (rated value) | E39-R1S | 1 | ||
| 5 m (100 mm) | E39-R2 | 1 | ||
| 2.5 m (100 mm) | E39-R9 | 1 | ||
| 3.5 m (100 mm) | E39-R10 | 1 | ||
| Small Reflector | 1.5 m (50 mm) | E39-R3 | 1 |
Note:When using a Reflector without a rated value, use 0.7 times typical value as a guideline for the sensing distance.
*Set the distance between the Sensor and the Reflector so that it is at least the value in parentheses.
